BETEC CAD.‘s B-40 Series Gas tight dampers are designed such that they can isolate sections of a ventilation system with a very high level of sealing (gas tight). This can be required for safety reasons in certain operational conditions. GTD-B-40 shut off dampers are designed so that after closure,even with failure of power supply to the actuator, the damper maintains the sealed closure, even in accordance with KTA 3601 (Guidelines for Nuclear Plant) and AO A60 (type approved) for Marine, Oil & Gas applications. The compact design and robust actuator mechanisms of these shut-off dampers enable them to be installed in any orientation.
